FIG. 5 shows a mold clamping part of a horizontal mold clamping die-casting machine which includes a fixed die plate 42, a movable die plate 43, a plurality of tie bars 40, and a mold clamping cylinder (not shown) and molds are opened and closed. The fixed mold 45 attached to the fixed die plate 42 and the movable mold 46 attached to the movable die plate 43 open, and the molded product 47 is moved to the movable mold 46.
, The product extruding device 48
Is mounted on the movable die plate 43. The product take-out device 44 is mounted on the upper part of the machine,
A product take-out arm device 54 that moves up and down between 46 and grips the biscuit portion 56 of the product 47 with the tip chuck portion 55;
A sliding device 58 for fixing the product take-out arm device 54 and moving it in the left and right mold opening and closing directions in the drawing, and a traveling platform 59 to which the sliding device 58 is attached, not shown It comprises an unillustrated unloading device for running a rail 60 erected between the column and the upper part of the machine. In the case of FIG. 5, the product take-out arm device 54 moves linearly, but various articulated robots combining the product take-out arm device and the carry-out device are also employed.

[0003]

When the molded product 47 is taken out by the product take-out device 44, the product take-out arm device 54 is lowered between the opened dies 45 and 46 and the movable die 46 is moved. Biscuit part 5 of product 47 attached to
The product extruding device 48 mounted on the movable die plate 43 is driven while the product 6 is being held by the chuck portion 55 at the tip thereof, and an operation of extruding the product 47 from the movable mold 46 is performed. The sliding device 58 to which the arm device 54 is fixed must be driven to be moved synchronously with the pushing operation of the product pushing device 48. The product pushing device 48 and the sliding device 58 each operate with an oil-pneumatic cylinder or the like. However, there is a problem that it is difficult to adjust the synchronous movement because of the independent drive system and the product take-out device is damaged in the case of synchronization failure. Also, open the molding machine mold,
It is necessary to provide an interlock with a sufficient margin so that the series of operation timings from lowering the product take-out arm device, grasping the product, pushing out the product, and raising the product take-out arm device do not interfere with each other, so that the idle time is accumulated. As a result, the cycle time increases and the productivity is reduced.

Therefore, the present invention makes it possible to perform synchronous movement by integrally engaging a sliding operation in the opening and closing direction of the product take-out device and a pushing operation of the product extruding device, which are performed during product extrusion. It is therefore an object of the present invention to provide a product take-out device which can solve the problem that the product take-out device is damaged due to synchronization failure and reduce the idle time between each product take-out operation to improve the productivity.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a product removing device for attaching a molded product to a mold, opening the mold, and removing the product from the molding machine. A slide table that is movable and installed on the side or floor of a die plate or a machine frame, a product take-out arm device mounted on the slide table, and extrusion of a product extrusion device mounted on a die plate of a molding machine. A product take-out device comprising a cylinder member and a linear actuator which is engaged between the extrusion cylinder member and the slide table and operates in a mold opening / closing direction, and which can be synchronously moved with the product extrusion device. .

[0006]

[Function] When a product is taken out by a product take-out device, a product take-out arm device is inserted between the two opened molds, and a product extruding device equipped on a die plate in a state where the product is held by a chuck portion. When the product is extruded by driving the product, the slide table on which the product take-out arm device is mounted and the extrusion cylinder member of the product extrusion device are integrally engaged via a linear actuator that operates in the mold opening and closing direction. Thereby, synchronous movement of the product take-out device and the product push-out device becomes possible.
